“There was absolutely no doubt that Lindsay was drinking, and the report that the alcohol monitoring service provided to Judge Revel was very detailed and extremely reliable,” a source close to the situation told RadarOnline.com.

We’ve also exclusively learned that Lindsay’s SCRAM bracelet appears to have been tampered with. The tampering would not have led to a false positive reading for alcohol, the source said.

“The (SCRAM) report also says that Lohan’s SCRAM bracelet had indeed been tampered with, and this is one of the reasons that Judge Revel determined that Lindsay violated terms of her bail,” the source told RadarOnline.com.

The time of the test will be compared to the SCRAM data by both the prosecution and Lindsay’s defense, the source told RadarOnline.com.

Despite reports that the probation department has cleared Lindsay, the judge in her case has not and that is the biggest hurdle for the actress. The source told RadarOnline.com that Lindsay’s urine test will not be accepted as gospel, due to the reliability of the SCRAM device.
